This study was undertaken to find out the incidence of rectal prolapse.
Ninety-nine patients operated on for rectal prolapse at Jyväskylä Central Hospital were studied. Patients operated between 1988 and 1998 were studied retrospectively from hospital records using chart review and thirty-five patients operated on between 1999 and 2002 were studied prospectively using our proctologic database.
The annual incidence of diagnosed complete rectal prolapse in the district of Central Finland was mean 2.5 (range, 0.79-6.08) per 100 000 population. There were ten men (10 percent) and 89 women (90 percent). Median age of the patients was 69 (range, 21-91) years. Forty-eight percent of the patients had concomitant cardiovascular disease and 15 percent psychiatric illness. Anal incontinence affecting quality of life was seen in 64 percent and constipation in 72 percent of patients. Constipation tended to be more attributed to difficult evacuation (72 percent) than to impaired bowel action (18 percent).
The annual incidence of rectal prolapse is 2.5 per 100 000 population. Rectal prolapse is associated with anal incontinence and constipation in majority of patients.
开展本研究以查明直肠脱垂的发病率。
对于约恩苏中央医院接受直肠脱垂手术的99例患者进行了研究。对1988年至1998年间接受手术的患者，通过查阅病历从医院记录中进行回顾性研究；对1999年至2002年间接受手术的35例患者，利用我们的直肠病数据库进行前瞻性研究。
芬兰中部地区确诊的完全性直肠脱垂年发病率平均为每10万人口2.5例（范围为0.79 - 6.08例）。其中男性10例（10%），女性89例（90%）。患者的年龄中位数为69岁（范围为21 - 91岁）。48%的患者伴有心血管疾病，15%伴有精神疾病。64%的患者存在影响生活质量的肛门失禁，72%的患者存在便秘。便秘更多是由于排便困难（72%）而非肠道蠕动功能受损（18%）所致。
直肠脱垂的年发病率为每10万人口2.5例。大多数患者的直肠脱垂与肛门失禁和便秘有关。
